Bracketing paradoxes—constructions whose morphosyntactic and morpho-phonological structures appear to be irreconcilably at odds (e.g., unhappier)—are unanimously taken to point to truths about the derivational system that we have not yet grasped. Consider that the prefix un- must be structurally separate in some way from happier both for its own reasons (its [n] surprisingly does not assimilate in Place to a following consonant (e.g., u[n]popular)), and for reasons external to the prefix (the suffix -er must be insensitive to the presence of un-, as the comparative cannot attach to bases of three syllables or longer (e.g., *intelligenter)). But, un- must simultaneously be present in the derivation before -er is merged, so that unhappier can have the proper semantic reading (‘more unhappy’, and not ‘not happier’). Bracketing paradoxes emerged as a problem for generative accounts of both morphosyntax and morphophonology only in the 1970s. With the rise of restrictions on and technology used to describe and represent the behavior of affixes (e.g., the Affix-Ordering Generalization, Lexical Phonology and Morphology, the Prosodic Hierarchy), morphosyntacticians and phonologists were confronted with this type of inconsistent derivation in many unrelated languages.
Bracketing Paradoxes in Morphology
Connectionism in Linguistic Theory
Connectionism is an important theoretical framework for the study of human cognition and behavior. Also known as Parallel Distributed Processing (PDP) or Artificial Neural Networks (ANN), connectionism advocates that learning, representation, and processing of information in mind are parallel, distributed, and interactive in nature. It argues for the emergence of human cognition as the outcome of large networks of interactive processing units operating simultaneously. Inspired by findings from neural science and artificial intelligence, connectionism is a powerful computational tool, and it has had profound impact on many areas of research, including linguistics. Since the beginning of connectionism, many connectionist models have been developed to account for a wide range of important linguistic phenomena observed in monolingual research, such as speech perception, speech production, semantic representation, and early lexical development in children. Recently, the application of connectionism to bilingual research has also gathered momentum. Connectionist models are often precise in the specification of modeling parameters and flexible in the manipulation of relevant variables in the model to address relevant theoretical questions, therefore they can provide significant advantages in testing mechanisms underlying language processes.
Morphology in Japonic Languages
Due to the agglutinative character, Japanese and Ryukyuan morphology is predominantly concatenative, applying to garden-variety word formation processes such as compounding, prefixation, suffixation, and inflection, though nonconcatenative morphology like clipping, blending, and reduplication is also available and sometimes interacts with concatenative word formation. The formal simplicity of the principal morphological devices is counterbalanced by their complex interaction with syntax and semantics as well as by the intricate interactions of four lexical strata (native, Sino-Japanese, foreign, and mimetic) with particular morphological processes. A wealth of phenomena is adduced that pertain to central issues in theories of morphology, such as the demarcation between words and phrases; the feasibility of the lexical integrity principle; the controversy over lexicalism and syntacticism; the distinction of morpheme-based and word-based morphology; the effects of the stage-level vs. individual-level distinction on the applicability of morphological rules; the interface of morphology, syntax, and semantics, and pragmatics; and the role of conjugation and inflection in predicate agglutination. In particular, the formation of compound and complex verbs/adjectives takes place in both lexical and syntactic structures, and the compound and complex predicates thus formed are further followed in syntax by suffixal predicates representing grammatical categories like causative, passive, negation, and politeness as well as inflections of tense and mood to form a long chain of predicate complexes. In addition, an array of morphological objects—bound root, word, clitic, nonindependent word or fuzoku-go, and (for Japanese) word plus—participate productively in word formation. The close association of morphology and syntax in Japonic languages thus demonstrates that morphological processes are spread over lexical and syntactic structures, whereas words are equipped with the distinct property of morphological integrity, which distinguishes them from syntactic phrases.
